IQmark Diagnostic Workstation Operation Manual

B. Thin Client Configuration

If you have a thin client environment, you can install the IQmark Diagnostic Workstation

software on the Terminal Server and operate the IQmark Digital ECG and/or the IQmark

Digital Spirometer through a thin client terminal.

The IQmark Diagnostic Workstation supports two thin client configurations. The IQmark

Virtual Channel Solution is appropriate when using Microsoft Windows based PCs as

clients. In this configuration, you can use either the USB or serial port versions of the

IQmark Digital ECG and IQmark Digital Spirometer products in high latency, limited

bandwidth network configurations. The following section describes the virtual channel

solution. The second possible configuration is to use the serial port version of the IQmark

Digital ECG, IQmark Digital Spirometer and IQmark VSM products and connect them to

client devices via COM port mapping. This configuration is appropriate when using non-

Windows thin client devices on low latency high-speed networks. The section entitled

Thin Client Using COM Port Mapping discusses this solution.

Setting up any application on a network environment typically requires special access

rights and knowledge of the network. Please have your network administrator install and

setup the IQmark Diagnostic Workstation to fit your office environment.

Thin Client Using the IQmark Virtual Channel Solution

The IQmark Thin Client Virtual Channel software provides the following advantages

over COM port mapping.

1. Operation over high latency, low bandwidth, high loss networks. For Microsoft

Terminal Services, the virtual channel provides a 10 to 1 improvement in

performance in latency tolerance over COM port mapping. For Citrix ICA the

performance improvement is approximately 40 to 1 in latency tolerance.

2. No COM port mapping is required.

3. It is possible to use the USB versions of the ECG and Spirometry modules.

4. Improved device auto-configuration and diagnostics.

 NOTE: The IQmark Virtual Channel Solution has specific requirements for

computer hardware, software and network performance. System

administrators must read the document entitled Application Note: Using

the IQmark Thin Client Virtual Channel Software before installing,

configuring and using this software in a thin client environment.

The following block diagram describes the IQmark Virtual Channel Solution. In this thin

client environment, the client computers must be running Windows XP SP2 or Windows

Vista.
